Abstract

The superior biocompatibility and bioactivity of hydroxyapatite (HA) ceramic has attracted much attention as a substitute material in bone grafting. In the present work, the HA was produce from bovine bone while zirconia powder was supplied by the China (Mainland) trading company. In this work, HA/ZrO2 biocomposite prepared with different wt % (0.0, 0.2, 0.4 and 0.8) of ZrO2 concentrate, sintered at 1250 °C, 1 h milling time. In this project, the bioactivity test was carried out by soaking the sample in simulated body fluid SBF solution, 7 and 15 days in an incubator maintained at 36.5 oC. For instance, bioactivity was studied by soaking the samples in the SBF solution followed by the SEM, EDX analysis as well as XRD. The SEM results showed the apatite on the surface of HA/ZrO2 biocomposite on a 7 days growth and when the immersion time increased to 15 days, the growth of apatite on the surface increased more. Other than that, the EDX showed that the covered layer on the surface was P and Ca as well as O. The XRD results showed that the soaked HA/ZrO2 biocomposite composed HA, α-TCP, β-TCP and ZrO2 and no other phases were detected. Recent Publications 1.
